Описание (английский):

This document specifies a test method for determining the resistance to elevated temperature cycling of thermoplastics piping systems for non‑pressure applications, inside buildings or buried in the ground within the building structure. This document is applicable to piping systems with components of nominal outside diameters up to and including 200 mm. Although limited to nominal outside diameters up to and including 200 mm, the test results may be extrapolated to products of larger nominal outside diameters from the same range.

Abstract

Overview

ISO 13257:2018 sets out the standardized test method for evaluating the resistance of thermoplastics piping systems to elevated temperature cycling in non-pressure applications. Thermoplastic pipes and fittings are often used in waste, soil, and drainage systems inside buildings or buried underground within the building structure. This standard ensures that such systems perform safely and reliably under repeated exposure to alternating hot and cold water, which can cause mechanical stress and deformation over time.

The method applies to systems with pipe and fitting components of nominal outside diameters up to and including 200 mm. Results may be extrapolated to products of larger diameters if they are from the same technical range.

Key Topics

Test Methodology: The standard details the laboratory procedure for subjecting test assemblies to cycles of hot and cold water to simulate real-use thermal variations. The key parameters include:
- 1,500 cycles of alternating hot (up to 93°C) and cold (as low as 15°C) water
- Monitoring for leaks and visual inspection for sagging after the test
- Use of precise temperature and sagging measurement devices
Test Assemblies: Procedures cover assemblies for pipes with and without integral sockets, for different diameters (≥40 mm and
